Neither human nor demon, the squamata Kartikeya haunts the corridors beneath New Jerusalem, like all lost souls a prisoner there. Marked by Hell, Kartikeya bears within it the bittersweet rage of those who have no side, no caste.

Claustrophobia: Furor Sanguinis is an expansion for Claustrophobia that introduces playing a single character, the squamata warrior Kartikeya. Components include one painted miniature, three new room tiles, a squamata board, one sheet of tokens, and five squamata dice as well as six new scenarios that pits this warrior against the humans or demons.
